An offer does not always need a spoken sentence or a signed letter to exist in the eyes of law. A bus that stops at your regular stop is making an offer just as much as a shopkeeper who tells you the price of a shirt out loud. The Indian Contract Act, 1872 recognises both these situations, and understanding the difference between them is one of the first things you need to get right before you move on to acceptance, consideration, or breach of contract.

What section 9 of the contract act says
Under the Indian Contract Act, 1872, an offer (or proposal) is when one person signals to another that they are willing to do or not do something, in order to get that other person’s agreement. This much is settled by Section 2(a) of the Act. But the Act goes a step further and tells us how that willingness can actually be signalled.
Section 9 of the Contract Act draws a clean line: if a proposal or its acceptance is communicated through words, spoken or written, it is called express. If it is communicated in any other way, through actions, symbols, or the circumstances surrounding a transaction, it is called implied. Both are equally valid in the eyes of law. The Act does not treat one as a lesser or informal version of the other; it simply describes two different routes to the same legal destination.
Express offers: when words do the talking
An express offer is the more obvious of the two. Someone states, out loud or in writing, exactly what they are willing to do. There is no guesswork involved because the terms are laid out in language that both parties can point to later if a dispute arises.
Oral offers
If A tells B, in person or over a phone call, that he is willing to sell his book for Rs. 50, that is an oral express offer. The moment the words leave A’s mouth and reach B, the offer exists in a form the law recognises, even though nothing has been written down.
Written offers
A written express offer takes the same idea and puts it on paper, in an email, a text message, or a formal letter. Businesses generally prefer written offers precisely because they leave a trail. If a disagreement later arises over what exactly was promised, a written document is far easier to rely on than someone’s memory of a conversation.
Implied offers: when actions speak louder than words
An implied offer is never announced in so many words. It is inferred from what a person does, or from the circumstances they set up, and a reasonable person observing the situation would understand that an offer is being made.
Everyday implied offers around us
You encounter implied offers constantly without noticing them. When a public transport service, a bus or an auto-rickshaw, operates on a fixed route at a fixed fare, it is making a continuing implied offer to carry any passenger who boards, according to legal commentary on Section 9. Nobody at the bus depot reads out an offer to you. The act of running the service on a public road is the offer itself.
An auction works the same way. When a bidder raises a hand or a paddle, no words are exchanged, yet contract law treats that gesture as an offer to buy at the stated price. The conduct carries exactly the same legal weight as if the bidder had shouted out the amount.
The coolie at the railway platform
A classic illustration used in Indian contract law textbooks involves a uniformed coolie at a railway station. If the coolie picks up a passenger’s luggage without being asked, and the passenger allows this to happen instead of stopping him, the law treats this as an implied offer of service by the coolie and an implied acceptance by the passenger. Training material published by the Indian Institute of Corporate Affairs uses this exact scenario to explain how conduct alone can create binding obligations. The passenger ends up owing payment for the service, even though not a single word about money was ever spoken.
Vending machines, self-service checkouts, and even a shop that keeps its shutters open during business hours work on the same logic. The circumstances themselves communicate willingness to contract, and the law fills in the rest.
Express offer versus implied offer at a glance
| Basis | Express offer | Implied offer |
|---|---|---|
| How it is made | Through spoken or written words | Through conduct or surrounding circumstances |
| Legal source | Section 9, first part | Section 9, second part |
| Ease of proof | Easier, since there is usually a record | Harder, since it relies on interpreting conduct |
| Typical setting | Business contracts, letters, advertisements | Public services, daily transactions, routine conduct |
| Example | A tells B he will sell his bicycle for Rs. 2,000 | A bus stopping at a designated stop for passengers |
Why the distinction matters for you
This is not just a definitional exercise for an exam answer. The distinction between express and implied offers shapes how disputes get resolved in real life. An express offer, because it exists in words, is usually straightforward to prove. Two people can look at a text message or a signed letter and largely agree on what was offered.
Implied offers are trickier. Since there is no explicit statement, courts have to look at the conduct of the parties and ask whether a reasonable person in that position would have understood an offer to exist. This is exactly the reasoning applied in the coolie example: the coolie’s uniform, his action of picking up the bag, and the passenger’s silence together create enough evidence of an offer and acceptance, even without a single word spoken.
For a business, this has practical consequences. A company that runs a self-checkout counter, a food delivery app that displays a menu with prices, or a courier service that picks up a package left outside a door, is making implied offers whether it intends to or not. Understanding this helps businesses in India think carefully about how their everyday operations, not just their signed contracts, can create legal obligations toward customers.
It is also worth remembering that an offer, whether express or implied, still needs to satisfy the other basic requirements of a valid offer. It has to be communicated, it has to show a clear intention to create legal relations, and its terms have to be reasonably certain. The method of communication, words or conduct, only affects how the offer is proved, not whether it is legally sound.
What do you think?
What do you think? The next time you board a shared cab or use a vending machine, can you spot the implied offer hiding in that everyday transaction? And do you think businesses in India rely too heavily on implied offers in situations where a clearer, express offer would protect both sides better?
